Titanium-6Al-7Nb Manufacturer and Supplier in India

HOME → Titanium Alloy → Titanium 6Al-7Nb

Titanium-6Al-7Nb (UNS R56700) is a vanadium-free, alpha-beta titanium alloy that was developed to meet the needs of vanadium-free, superior mechanical properties, and biocompatibility. It is a mixture of about 6% Al and 7% Nb and the remaining material is Ti. The alloy has high strength to weight ratio and excellent fatigue resistance, toughness and corrosion resistance. It is particularly suitable for orthopedic implants, dental implants, surgical components, medical devices and other applications that require biocompatibility. The Ti-6Al-7Nb composition is also known for ASTM F1295 wrought Ti-6Al-7Nb alloy for surgical implants. Sachin Steel Centre produces and distributes Titanium 6Al-7Nb products in various forms, sizes and specifications for challenging medical and industrial applications.
